To alt fw/Lm it may concern:

Be it known'that I, WESTON M. FULTON, a citizen of the United States of America, and a resident of Knoxville, Tennessee, have invented a new and useful Improvement in Radiator-Casings, which invention is fully Yset forth in the following specication.

This invention relates to radiator jackets, and more particularly to jackets of this class in which a thermostatic device,` subject to room-temperature, is used for automatically operating dampers for controlling the ow of heated air'through the jacket.

The -invention has for its object to provide a radiator casing of the above type in which the thermostatic element shallbe free from sudden changes of temperature such asimay arise from accidental cold drafts'from open windows; and be protected from the direct heat of the radiator as well as from stray heated convection currents therefrom, while at the same time it shall besubjected to air from the room at or near the average roomtemperature. f

My invention enables the above objects to be secured in an effective manner and,

i vbroadly stated, consists in providing in a damper-controlledl radiator casing an chamber or extension of the casing partitioned from the main part of the casing and into which air ,at average temperature of the room is drawn by convection currents set up in another part of the chamber, and locating in the chamber a lthermostat for operating the dampers Where it may be subjected to the incoming cool air and insulating the same from the heating effects of the main chamber. l

By way ofY illustrating one cons'tructional forni of my invention, I provide a radiator casing, preferably one having a hood, with an extension or chamber closed at the bottom by an insulating Hoor which extends beyond the pipe.J connections to the radiator, and having an air inlet in the end Wall near lts top. The space in this extension is p referably partitioned from the main space 1n the casing. by means of a specially formed end sectionof the radiator consisting of a hollow wall which performs the double function of I a heating section and a. partition. This section is preferably located at the inlet end of the radiator. In this chamber is located a vertical insulating partition opposite the end section of .the radiator and extending to near 'the Hoor of the chamber: This'partiloiivides the chamber into two vertical compartments communicating at their bottoms. The outside compartment near its top is open to vthe room, and the inner compartment is open to the hood space but is out ofrfrom the main radiator space by the end wall of the radiator. stitute a U-shaped conduit, one branch of which is in heat interchangingrelation with the radiator end section and opens into the The two compartmentsconx hood of the casing; the other branch is open.

to the room. To secure the maximum ditference of temperature between these two branches, whereby vigorous circulation of air through the chambers may be secured, the partition separatihg the chambers is made of non-heat conducting material, such as cork. This also has the effect of shielding thethermostatic device from the heat of the radiator and enables the device to respond more nearly to the temperature of the air entering theconduity from the room. To avoid transfer of heat by conduction through the connections between the thermostatic device and the dampers inthe casing, the connections \vhicii`""pass through the wall separating the two spaces are preferably made of heat insulating material, or, if of metal, means are provided for circulating cool air about the same. To avoid hot air escaping around the connection, I preferably provide a packing joint through which the connection lnay work. The thermostatio device vis further protected from heated air 'in the hood by making the top Wall closing'the compartment containing this device of heatinsulating material.- As a result of this construction, the thermostatic device is enabled to control the dampers of the casing practically uninfluenced by all forms of heat emanating from the radiator and is affected Only by air from the room which represents veryA nearly the ,average room-temperature.

In order that the invention may be more readily understood, reference is had tothe accompanying drawings which illustrate one mechanical embodiment of the inventive idea. The drawings are merely intended to 'assist the description and not to define the limits of the invention. A

Figure 1 is a longitudinal vertical sectional view of a'portion of a radiator casing constructed in accordance with my improve ment and showing heating sections in eleva'- 'zov the casing broken away to show the interior arrangement; and.`Fig. 4 is a top plan view with the hood removed, showing the arrangement of dampers and other parts.

In the drawings, Fig. 1 exhibits three radiator sections 1, 2 of the inclined ribbed type, and anend section 3 in the form of a hollow plate or wall, the bottom of which is connected with a pipe 4 of the heating system and preferably theV inlet pipe. 5 is an end extension of the radiator casing adapted to tit snugly around the heating section 3 which separates the extension from the main radiator space of the casing and is surmounted by an extension .of the hood 6 of the casing. The bottom of this extension is closed by a Hoor 7 consisting of a plate of sheet metal lined with insulating material, such as cork or the like, and lprojects above and beyond the inlet pipe connection 4. The space within the extension is divided into compartments 8 and 9 by means of a depending partition 10 which terminates just above the floor 7, thereby permitting communication at this point between the compartments. The compartment 8 is covered by a wall 11 of insulating material like that y mentioned, and has an opening 12 for admission of air at average room-temperature provided near the top and in the end wall of the extension. Compartment 9 which is heated by the radiator opens into the hood space above it. 13 is a thermosensitive deJ .vice adapted to be supported in compartment 8 near the entrance 12 and is pro.

vided with a connection 14 preferably of heat-insulating material, such as wood or other non-heat conducting material, which Vpasses through the partition wall 10 and is pivotally connected to a damper-operating lever A15 having operating connections with dampers 16 which control openings between the space heated by the radiator sections and the hood.' To prevent heated air from passing baclcfrom compartment 9 into coin- Vpartment 8 and affecting the -tlierniostatic device, the wall 10 is preferably provided with a packing box throu h which the rod 14 may tightly work. To acilitate the heating of air in compartment 9 and hasten air circulation past the thermostatic device, ribs 18 are provided on the md section 3 of the radiator.

The vertical walls of the casing extension may, and preferably are, of sheet metal of single thickness, but their edges where they jqin the main casing should',be heat insulated therefrom by means of asbestos strips 18', or similar material, for the purpose of reducing as much as possible conduction of heat from the casing Walls to the walls of the extension.

The operation of my improvement will be readily understood from the above description and, briey stated, is as follows:- Steam or hot water having been admitted through inlet pipe 4 to the radiator, the

the incoming air from the room, and operates ythe dampers through its connections. The partition 10 effectively insulates the device rom the heating effects of the radiator and heated air in compartment 9. The floor 7 prevents convection currents set up around the heated connection 4 from inding their way to opening 12 and thence to the thermostatic device. The top wall of compartment 8 shields the device from the heated air in the hood and heat conduction through connection 14 is avoided by making this connection of insulating material, while the side walls of the extension are insulated from the body of the casing by insulating strips 1S.
